  • This study finds surface color and functions of natural dyeing from Chamaecyparis obtusa leaves which help cure skin problems such as atopic dermatitis. This study also seeks to find dyeing properties and functions of natural colorants derived from Chamaecyparis obtusa and Rubia tinctorum on silk. Dyeing properties and functions are compared between silks dyed with Chamaecyparis obtusa and silks composite-dyed with Chamaecyparis obtusa and Rubia tinctorum. The comparison examines the feasibility of developing healthy and high functional fabrics and wellness of fashion merchandises. Silk dyeing with Chamaecyparis obtuse leaves yields yellow and double coloring from Chamaecyparis obtusa; however, Rubia tinctorum yields yellow/red on silks. Silks dyed with Chamaecyparis obtusa and silks composite-dyed with Chamaecyparis obtusa and Rubia tinctorum show a high level on dry cleaning, ultraviolet protection and deodorization. Especially, the dyed silks from leaves of Chamaecyparis obtusa show a 99.7% antimicrobial effect against staphylococcus aureus ATCC 653B. Silks composite-dyed with Chamaecyparis obtusa and Rubia tinctorum are better known for medicinal herb for dermatitis, and natural colorant, Rubia tinctorum does not improve significantly functions compared with silks dyed with Chamaecyparis obtusa. However, the dyeing properties improve by composite dyeing. This implies that ways to maximize effects of tie-dyeing technique could be developed.

  • This study measured dyeing properties under different dyeing conditions and levels of antimicrobial activity when man-made fibers are dyed with gallnut, including rayon, tencel, tencel blended fabric, soybean fiber, and nylon non-mordanted. The dye up-take (K/S), color ($L^*a^*b^*$), and color differences (${\Delta}E$) were measured with a colorimeter, and the number of bacteria present in the dyed fabrics were determined using Staphylococcus aureus and Klebsiella pneumonia as strains. The results are as follows: First, the optimal dyeing conditions for man-made fibers dyed with gallnut are 60 minutes of dyeing time and a $80^{\circ}C$ dyeing temperature. Second, gallnut dye is most effective on soybean fiber and then, in descending order of effectiveness, on nylon, rayon, tencel, and tencel blended fabric. This means that dyeing properties of nitrogen containing fibers are excellent when using gallnut. Third, all man-made fibers are dyed brown with gallnut. This implies dyeing possibility of man-made fibers about gallnut dye, so development and supply of natural dyed goods of man-made fibers can be increased. Fourth, in all man-made fibers dyed with gallnut extract, both Staphylococcus aureus and Klebsiella pneumonia show 99.9% reduction ratios of fungistasis, which indicate antimicrobial activity. Therefore, safe, functional, man-made materials can be developed to relieve symptoms from and treat patients with skin ailments.

  • This research investigates the application of ZnO (zinc oxide) nanoparticles and $TiO_2$ (titanium dioxide) nanoparticles to polypropylene nonwoven fabrics via an electrospinning technique for the development of textile materials that can decompose harmful gases. To fabricate uniform ZnO nanocomposite fibers, two types of ZnO nanoparticles were applied. Colloidal $TiO_2$ nanoparticles were chosen to fabricate $TiO_2$ nano- composite fibers. ZnO/poly(vinyl alcohol) (PVA) and $TiO_2$/PVA nanocomposite fibers were electrospun under a variety of conditions that include various feed rates, electric voltages, and capillary diameters. The morphology of electrospun nanocomposite fibers was examined with a field-emission scanning electron micro- scope and a transmission electron microscope. Decomposition efficiency of gaseous materials (formaldehyde, ammonia, toluene, benzene, nitrogen dioxide, sulfur dioxide) by nanocomposite fiber webs with 3wt% nano-particles (ZnO or $TiO_2$) and 7$g/m^2$ web area density was assessed. This study shows that ZnO nanoparticles in colloid were more suitable for fabricating nanocomposite fibers in which nanoparticles are evenly dispersed than in powder. A heat treatment was applied to water-soluble PVA nanofiber webs in order to stabilize the electrospun nanocomposite fibrous structure against dissolution in water. ZnO/PVA and $TiO_2$/PVA nanofiber webs exhibited a range of degradation efficiency for different types of gases. For nitrogen dioxide, the degradation efficiency was 92.2% for ZnO nanocomposite fiber web and 87% for $TiO_2$ nanocomposite fiber web after 20 hours of UV light irradiation. The results indicate that ZnO/PVA and $TiO_2$/PVA nano- composite fiber webs have possible uses in functional textiles that can decompose harmful gases.

  • This study examine closely conditions of costume between the Modernized period and Liberation with newspaper materials. Because newspaper generally appear society conditions in those days on rapid and across-the boad basis. The Modernized period is extremely change among history of costum (ordinance prohibiting top knots, allowance of foreign clothes putting on). Because this change have been spontaneously not by internal desired but Western input by the strong nation of imperialism to enclose Chosun, they was accepted by the general public later under the rule of Japaneses Imperialism. Consequently, study of costume play an important part periods between the Japanese annexation of Korea and Liberation. This study apply to newspaper characteric for costume, and closely examine an important costum condition of those days next time, and present costume material in those days that composed the account catalog appeared periods between the first publication(1920) of the Dong A II Bo, and in the year 1945, it is as follows. 1. Foreign clothes of men generally accept the general public on look at from form change, in the 1920's had come short Jackets and narrow throusers into fashion, in the 1930's had come trousers of generous waist band with broads shoulder and long Jackets. Catalog of Major clothes is as follows; Spring coat, Jacket, Vest, Shirt, etc. While pants had come trousers into fashion 2. Functional characteric of Foreign clothes was the possible acceptance of women's foreign clothes. It relate with much discussion to improve Korean development in those days and substitute foreign clothes for Korean clothes because of institence in those days to improve functional clothes life. 3. An improvement women's Korean clothes generally take aim at women's nipple liberation, substitute vest waist for skirt waist, appear seamless one-piece skirt of shade length, and long dress length of Jacket. 4. Children's clothes give an account of functional and sanitary conditions, handling method, washing method. 5. Clothes materials give account of foreign clothes material, artificial silk, furs, cotton fabrics, and etc. 6. Clothes management give an account of washing, keeping method, washing method of foreign clothes, and keeping of furs. 7. The hair generaly had come short hair into fashion in men's case, while accounts on long hair fashion of foreign nation effect in case of women. 8. Describing on beauty care manage primary beauty care, reform, plastic operation, and shade beauty care. Ideal beauty care deal with natural and dignified buauty care. 9. Accesaries (hat, handbag, handkerchief, gloves) change with fashion of clothes, it rapid more than clothes fashion. 10. On encouragement of abolition of white clothes and putting on dyeing clothes, because of economic defect of white clothes, psychology and beauty consequently, white clothes is on the rise abolition. In national level almost substitute dyeing clothes for control and improvement of people of all social standings consequently, dress and its ornaments conditions in those days analyzed account of Dong-A II Bo accept the foreign clothes that introduced internal country of the whole century, and substitute dyeing for white clothes. Costume condition in those days appear the mixed conditions of Korean clothes and Foreign clothes. In the 1920's is the first consideration dress and its ornaments form of Korean clothes. As later goes on foreign is given much weight in the whole clothes life. Account of foreign clothes managemental ways appear in the 1920's, while those facts prove the point that appeared the account that always dealed with concrete content of foreign fashion in the 1930's.
